The decomposition of T-Stoff into hot steam and oxygen caused by the addition of the catalyst Z-Stoff (an aqueous solution of permanganates) was used to drive the split-tube steam catapults which launched the V-1 flying bomb.[4]

Similarly generated steam was used to drive the turbopump in the German V2 rocket, and the pumps in several other rocket engines. The turbopump was used to transport fuel and oxidizer liquids under pressure to the rocket engine of the V2.[5]

Another of T-Stoff's many uses was to be combined as the oxidizer, with C-Stoff (methanol-hydrazine-water mixture) as the fuel, in the bipropellantWalter HWK 109-509 engine of the Messerschmitt Me 163 and Messerschmitt Me 263, at a ratio of approximately 3.1 parts T-Stoff oxidizer to one part C-Stoff fuel. Because the two substances were so visibly similar, a complex testing system was developed to make sure that each propellant was put into the correct tanks of the Messerschmitt Me 163. This was because T-Stoff and C-Stoff are hypergolic propellants: they spontaneously ignite when mixed at normal temperatures. Even slight contamination between the T-Stoff oxidizer and the C-Stoff fuel was likely to cause an explosion.

Catalytic decomposition of T-Stoff by Z-Stoff was also used as a monopropellant in several "cold" Walter rocket engines, including early versions of the engine for the Me 163A, and rocket-assisted takeoff pack engines like the Walter HWK 500.

Because of its extreme oxidizing potential, T-Stoff was a very dangerous chemical to handle, so special rubberized suits were required when working with it, as it would react with most cloth, leather, or other combustible material and cause it to spontaneously combust.
